Is my ozone working?
« on: December 13, 2007, 09:34:08 pm »
How do you tell for sure if your ozone is working?  I have a J345 and I didn't notice the bubbles coming out from the heater return like it usually does.

The bose injector for your Ozonator could be clogged.  You'll probably be able disconnect the top hose and dislodge any of the build up with a pin or anything with that small diameter.  If that doesnt do it then you may have to soak the injector.

Whenever I lost the bubbles, my ozonator check valve needed replacing.  To check...remove check valve from small diameter tubing and blow (do not suck) through.  You should be able to blow one way and not the other.  If you can't blow both ways, that is most likely your problem.  Be prepared for the nasty taste.

It could be as simple as a dirty filter.

First, focus on the bubbles.  Take the filter out, if your bubbles resume, the filter is restricting gallons per minute.  Second, as suggested, remove the feeder line to the injector, bubbles yes or no?  If no, Continue to work back through the check valve until we discover WHAT is stopping the bubbles.

It should be a simple diagnostic process to find out what happened to the bubbles that "deliver" ozone.

There is a direct relationship to GPM and the ability to draw a venturri action.  Your gpm's are reduced, OR you delivery system is blocked.

I agree with these responses.  

One other thing to point to restricted flow somewhere - even if your ozone system was not working, you'd still be getting bubbles.  The bubbles would just be air, though.  So, since you are not even getting bubbles, it points to a flow restriction somewhere.

Don't ever stick the ozone tubing in your mouth. The acid that builds up will cause serious chemical burns!

Thanks for all the responses.  The filters are fine because I just cleaned them recently.  In regards to the check valve and feeder line...looks like I need to remove the cover to the control panel...but after that I'm lost.  Where is the check valve and what is involved in replacing it?

Brings up an interesting question...I assume I could simply call the dealer and have them come out and fix it.  Tub is 6 months old so should be covered under warranty.  Right?

That would be an assumption, take your filters out first.  Recently is ambiguous and filters do restrict flow and flow is not covered under warranty.

With your particular spa and factory ozonator, it is most likely either a kink or blockage in the ozone tubing, the check valve or the Mazzei injector.  The check valve is most prone to failure.  It is very easy to check.  If you remove your front cabinet panels you should be able to locate the ozonator itself.  It should be a gray or blue box approx 8" x 5" with a 1/4" tube comming out of it along side a short 1/4" tube for air to enter.  Follow the long tube.  It should form a loop above the water line and end up at a special Tee at the water return line.  This tee is the Mazzei injector.  Somewhere along the 1/4" tubing there should be at least one check valve.  It is a small plastic device.  Sometimes the Mazzei injector can foul up and needs to be freed or cleaned up.  The only way you will know if your check valve is bad is to blow through it.  If you're nervous about the nitric acid, attach a clean short length of tubing and blow though that.  Your ozonator should blow bubbles whether the ozonator itself is working or not.  The bubbles are only an indication of the Mazzei injector and the tubing in good shape and enough water volume to allow the injector to work properly (thus the dirty filter issue).

 You could also put your hand on the ozonator and feel it running, main pumps should be off for this.

 Any chance you recently had a power outage??  That can allow water to siphon back up the 1/4" tube and get past the check valves, which does happen once and awhile.  

 I have seen some spas, that whoever installed the ozonator left the 1/4" tube on the floor inside the cabinet, instead of coiled up above the waterline, and it actually will siphon all the water out of the tub, through the ozonator.
